DEVICE FOR CLAMPING PATTERNS ON GOODS.

SPECIFICATION forming part of Letters Patent No. 288,410, dated November13, 1888.

Application filed June 22, 1883.

To LtZZlUibOWb it may concern:

Be it known that I, GIDEON A. CLOSE, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inDevices for Clamping Patterns on Goods; and I do hereby declare thefollowing to be a full, clear, and exact de seription of the invention,such as will enable others'skilled in the art to which it appertains tomake and use the same.

My invention relates to certain novel and useful improvements in devicesfor clamping patterns on goods for the purpose of holding the latterduring the process of cutting, and has for its object to provide such adevice as shall be simple in its construction and ready in adjustment,while at the same time its action shall be positive; and with these endsin View my invention consists in the details of construction andcombination of elements hereinafter fully explained in detail, and

then specifically designated by the claims.

. In order that those skilled in the art to which my inventionappertains may understand more fully the construction and operation ofmy improvement, I will proceed to describe the same in detail, referringby letter to the accompanying drawings, forming apart of thisspecification, in which- Figure l is a side elevation of my improvementin operative position; Fig. 2, a vertical section of what will behereinafter referred to as the block, and showing the swivel-eonnectionbetween the latter and thestandard; Fig. 3, a similar view of I theclamping-bar, showing a similar connection with the presserfoot; Fig. 4,a vertical section with the clamping-bar broken away, and showing thearrangement of the lock'and jam nuts around the said bar 5 Fig. 5, afront elevation, showing the manner of attaching the clamp to thecollar-nut and the guide-arm; and Fig. 6, aplan view, showing thepresser-foot clamped down on a pattern. a

Similar letters denote likeparts in the several figures of the drawings.

A is the standard, which is held in an upright position within sockets Bby means of set-screws 0, passed through said sockets,

which latter are bolted to the cutting block or table. At the upperportion of this stand- (No model.)

ard is a block, D, which is swiveled to said standard in any ordinaryway, as plainly shown at Fig. 2. E is a supportingarm, which is passedthrough a longitudinal opening in the block (see Fig. 2) in such amanner as to slide freely.

F is the clamping-bar, extending through the supporting-arm, so astol1ave a free V61" tical play therein. G is an elbow-lever pivoted tothe supporting-arm, and with its elbowprojeetions H toggle-jointed withthe rods I, as seen at Figs. 1 and 5. The rods I are pivoted at theirlower extremities to a collar, J,

011 the bar F, for the purpose presently explained. This collar issupported by nuts K L, traveling on the bar F, the latter nut acting asa lock to keep the former from working down, all of which will bereadily understood by reference to Figs. 1 and 4.

M is the presser-foot, swiveled in any ordinary manner (see Fig. 3) tothe clamping-bar.

N is a collar on the upper portion of the bar and resting upon thesupporting-arm.

O is a coil spring confined on said bar between the collar N and acrosspin, I.

The operation of my improvement is as follows: The cloth or other fabricwhich is to be cut is placed on the cutting block or table in as manylayers or thicknesses as desired. The pattern is then placed over andupon the cloth, 8w. and the supporting-arm pulled out, pushed in, orswung around, as the case may be, in order to bring the clamping-bar inposition, so that the presser-foot will be in the proper position abovethe pattern. The lever G is now depressed, and the elbows H and rods Iwill straighten out, thereby forcing down the clamping-bar, so that thefoot M presses the pattern firmly against the goods, and the latter cannow be cut around the pattern without any danger of slipping. The

.setting up the nuts K L, which will cause the elbows H and rods I toform a more acute angle in their normal position.

The standard A may be raised or lowered by simply loosening the screws Gand sliding it within the sockets B, and the normal vertical position ofthe clamping -bar adjusted thereby. This latter adjustment is especiallydesirable in order to bring the presser-foot to a certain plane abovethe goods, where the clamping mechanism can operate readily, and thisplane depends, of course,on the thickness of the goods to be out. Incutting around large patterns the presser-foot may be readily shifted toany part of the pattern, if desired, in order to get more pressure atthe particu lar point; also, my improved device may be used with greatfacility in cutting around eX- tremely long patterns, since thesupportingarm may be turned in any direction and moved throughout itswhole length and the presser-foot shifted accordingly.

Prior to my invention it has been common to nail the patterns down onthe goods through the cutting-block; but this not only consumedconsiderable time both in driving in and extracting the nails, but thegoods themselves were necessarily mutilated thereby, and very oftenspoiled entirely. My invention overcomes these difficulties and does thework in less time and without marring the goods in the least.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a clamping device, as described, the clamping-barswiveled to thepresser-foot and bowed at its lower portion, and operated in a verticalplane by a toggle-jointed lever, sub stantially as set forth.

2. The vertically-adjustable standard provided at its upper extremitywith swiveled block, in combination with the supportingarm arranged toslide horizontally within said block, and clamping-bar having attachedat its lower extremity a swiveled presser-foot, 5 and operated in avertical plane by a togglejointed lever, substantially as described.

3. In a device for clamping patterns onto goods, aclamping-bar operatedin a vertical plane by a togglejointed lever, and having attached at itslower extremity a swiveled presser-foot, in combination with anadjustable swiveled supporting-arm, substantially as set forth.

4. In a device for clamping patterns onto goods, an adjustablesupporting-arm, in combination with a clamp-bar operated in a verticalplane by a toggle-jointed lever, substantially as described.

5. In a device for clamping patterns on goods,- a presser-foot swiveledto aclamp-bar, in combination with an operating-lever and a swiveledsupporting-arm, as set forth.

(5. The clamp-bar, bowed as described, near its central portion, incombination with a swiveled presser-foot, substantially as described.

7. The combination of the clamp-bar F, presser-foot M, spring 0, collarN, supporting-arm E, collar J, nuts K L, toggle-jointed lever, swiveledblock D, and standard A, sub stantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GIDEON A. CLOSE.
